The ability of presentation is frequently considered as one of core competencies for higher educated professionals. It is widely concerned by the field of higher education and work. However, at present, the domestic colleges and universities still lack adequate pro-fessional courses and practice opportunities to help learners enhance oral presentation ability. This study used self-assessment and peer assessment (SAPA) to help students develop the oral presentation ability in blended learning courses in a Chinese university. The goal of this study was to examine students’learning experience and perceptions of SAPA. Both quantitative and qualitative data were collected and analyzed. Our results showed that the SAPA method helped and facilitated the development of students’ oral presentation ability. We also found that multiple sources feedback, the involvement of peers during the assessment, and multiple strategies for deepening self-reflections are crucial for developing oral presentation ability.
